Abstract: There is provided an optical waveguide device including: a substrate; an optical waveguide formed on the substrate; and a working electrode that controls a light wave propagating through the optical waveguide, in which the working electrode includes a first base layer made of a first material, a first conductive layer on the first base layer, a second base layer made of a second material different from the first material, which is on the first conductive layer, and a second conductive layer on the second base layer, and an edge of the second base layer is covered with the second conductive layer, in a cross-section perpendicular to an extending direction of the optical waveguide.

Abstract: Provided is a solid-state image capturing element including a semiconductor substrate and first and second photoelectric conversion parts configured to convert light into electric charge. The first and the second photoelectric conversion parts each have a laminated structure including an upper electrode, a lower electrode, a photoelectric conversion film sandwiched between the upper electrode and the lower electrode, and an accumulation electrode facing the upper electrode through the photoelectric conversion film and an insulating film.

Abstract: A vehicle battery mounting structure has: a battery frame lower member that is made of resin, and that is disposed at vehicle transverse direction inner sides of energy absorbing members provided at a lower side of a floor panel, and that, together with a battery frame upper member, structures a battery frame that supports a battery; a lower ductile member having a lower main body portion that is joined to vehicle transverse direction outer side end portions of the battery frame lower member, and lower flange portions that are fixed to a bottom surface side of the floor panel; and inclined walls that are formed at vehicle transverse direction outer side end portions of the battery frame lower member, and that are inclined from vehicle transverse direction outer upper sides toward vehicle transverse direction inner lower sides.

Abstract: The present invention provides a vehicle battery mounting structure including: a lower frame made of fiber-reinforced resin that has a first open portion for water drainage and configures, together with an upper frame, a battery frame that supports a battery; a lower reinforcement made of metal that has a second open portion for water drainage having a smaller open area than the first open portion, the lower reinforcement being joined to the lower frame in a state in which the second open portion is communicated with the first open portion; and an insulating grommet that is formed in the shape of a ring having an upper flange and a lower flange and that is disposed at the lower reinforcement as a result of a peripheral edge portion configuring the second open portion of the lower reinforcement being fitted between the upper flange and the lower flange.

Abstract: Lithium cobaltate forming the positive electrode of a lithium secondary battery is subjected together with lithium metal to reducing reaction in molten lithium chloride to produce lithium oxide and to precipitate and separate cobalt or cobalt oxide. The lithium oxide is subjected to electro-deposition in molten lithium chloride contained in a lithium electro-deposition tank provided with an anode and a cathode to recover lithium metal deposited on the cathode.
